Hi guys. How do you feel about an enhancement to Rails' *delegate *method that enables us to define an arbitrary value which is bound to be returned whenever the delegation target is *nil* ?
I've came across an use case on which I was required to do so. What I did was include the *on_nil: *option to *delegate*. I can use this new option the value that should be returned. The value can be either a literal or a Proc. When *on_nil *is not supplied the current behavior is followed (i.e. *nil *is returned). Here is an example: class User < ActiveRecord::Base > has_one :profile > delegate :age, to: :profile, allow_nil: true, on_nil: 21 > end > User.new.age # 21 Do you guys think this would be an useful enhancement to Rails' core ?
